Blockchain
development services.

Smart contracts, tokenisation, custody integrations, and regulated digital-asset workflows.

Brief us See work
What we build

We build blockchain applications — smart contracts on Ethereum / L2s / Solana, tokenisation platforms, custody and exchange integrations, and regulated digital-asset workflows for institutions.

How we run this kind of work
01 · Problem

Blockchain done badly is a security incident waiting.

Smart-contract bugs lose money and reputation simultaneously. The discipline is high; the operations practice is higher. Institutional use cases require audit, MEV awareness, custody integration, and a regulatory posture.

02 · Approach

Engineering & auditing as one program.

Solidity / Rust contracts with property-based testing, formal verification where appropriate, third-party audit before mainnet, and a deployment plan that includes a kill-switch.

03 · Outcome

On-chain systems institutions can actually use.

Audited contracts. Production deployment with monitoring. Custody and exchange integration. Compliance posture documented.

What we ship.

6 modules · extensible
F-01

Smart contracts

Solidity (EVM), Rust (Solana / Polkadot), CosmWasm (Cosmos) — with property-based testing and audit.

F-02

Tokenisation

ERC-20, ERC-721, ERC-1155, and security-token frameworks (ERC-3643 / 1400).

F-03

DeFi protocols

AMMs, lending, perpetuals, derivatives — engineered for security and gas efficiency.

F-04

Custody & exchange

Integration with Fireblocks, BitGo, Anchorage, Copper, and major CEXes via REST/WebSocket.

F-05

L2 integration

Arbitrum, Optimism, Base, Polygon zkEVM — and cross-chain bridge integration where required.

F-06

Regulated workflows

KYC/AML integrated workflows, transaction-screening, and reporting for regulated digital-asset operators.

Blockchain development FAQs.

Q-01Which chains do you work with?
Ethereum + L2s (Arbitrum, Optimism, Base, Polygon), Solana, Cosmos chains, and Sui/Aptos. Selection driven by use case.
Q-02Do you do smart-contract audits?
We coordinate third-party audits and run internal pre-audit reviews — Slither, Mythril, Echidna, Halmos. We do not self-audit production code.
Q-03Tokenisation for real-world assets?
Yes — ERC-3643 / 1400 security-token frameworks, KYC-gated transfer, and regulated registry integration.
Q-04Custody integration?
Yes — Fireblocks, BitGo, Anchorage, Copper. Most institutional engagements include one.
Q-05Regulated digital-asset workflows?
Yes — KYC/AML, transaction screening (Chainalysis, TRM, Elliptic), and reporting.
